BUSHING-REMOVER.

Specification of Letters Patent.

Patented Oct. 10, 1916.

Application filed April 22, 1916. Serial No. 92,939.

To all whom it may concern:

Be it known that I, JOHN J. MGGUCKIN, a citizen of the United States, residing at No. 633 Fifty-fourth street, borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Bushing-Removers, of Which the following is a specification.

My invention relates to a tool which is adapted to be used in forcing out bushings from their places in sleeves or hubs; and my improvements are particularly directed to means forsimply and effectually establishing a gripping connection between the tool and the bushing, whereby the latter may be dislodged from its seat by force applied to the tool, the particulars of my invention being hereinafter pointed out andclaimed.

In the drawings Figure 1 is a longitudinal sectional view of a hub provided with bushings, and shows my improved tool locked in place within one of the bushings; Fig. 2 is a perspective view of the tool; and Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. 1, looking to the left.

Corresponding parts are designated by similar reference numerals in all the figures.

The tool consists essentially of a stock 2, which is provided atone end wth a slightly expanded gripping portion 3, provided with a series of flanges 4, 4, 4, having abrupt forward faces and rearwardly sloped edges, as shown in the drawings. The end of the tool is beveled ofi' on one side as at 5, and a locking key 6. is provided, which has a beveled side 7, complementary to the beveled side 5 of the stock, and a semi-cylindrical side 8, corresponding substantially to the interior curve of the bushing. The key 6 is also provided with a head 9 which afl'ords suitable means for driving the key into place and for withdrawing it when desired.

In use, the shank-2 is slipped into position within a bushing, as 10, of a hub. or

. housing, as 11; and the key 6 is then driven into the bushing, because the shank will be driven down against the wedge, and the flanges l, I will be forced very positively against the bushing, toward which, because of their configuration, they present biting edges. Consequently, such a firm grip will be established between the tool and the bushing that the latter may be readily driven out of its socket, carrying with it the tool, which, because of the shape of its shank, may pass entirely through the hub or housing and be withdrawn therefrom with the bushing. The tool may afterward be separated from the bushing byknocking out the key 6, or by inserting a suitable instrument above the key and against the end of the shank and driving the latter backward off of the key and out of the bushing.

By means of my improvements I obtain a Having thus described my invention what I claim and desire to secure byv Letters Patent of the United States is: I

1. The combination, in a bushing remover, of a shank provided at one end with a beveled side and with a series of biting flanges, and a locking key having a beveled side adapted to operate against the beveled side of the shank.

2. The combination, in a bushing remover, of a. cylindrical shank provided at one end with a beveled side and with a series of biting flanges having substantially vertical forward faces and backwardly sloping rearward faces, and a locking key having a beveled side adapted tooperate against the beveled side of the shank.

3. The combination, in a bushing remover, of a shank provided at one end with a beveled side and with a series of biting flanges, and a locking key having a beveled side adapted to operate against the beveled side of the shank and a semi-cylindrical side adapted to bear against the interior curve of a bushing.

4. The combination, in a bushing remover, of a cylindrical shank provided at one end with a beveled side and with a series of biting flanges having substantially vertical forward faces and backwardly sloping rearhead.

5. The combination, in a bushing remover,

V of a cylindrical shank having a bevel at one side terminating with an outward curve, and on the other side. a series of biting flanges,

and a locking key having a beveled side adapted to operate against the beveled side of the shank.

6. The combination, in a bushing remover,

7 of a shank provided at one end wth a beveled side and with a series of biting flanges, and a locking key having a beveled side terminating with a curve adapted to operate against the beveled side of the shank.

7. The combination, in a bushing remover,-

of a body provided with a beveled side and With a series of biting fingers, and a look.

ing element having a beveled side adapted to operate against the beveled side of the body, and means for applying force longitudinally to the body.
